The method comprises dividing one and the same hairpin coil (2), fixed between two conductive sheets (3, 4), into two sections (G, F) of different refrigeration power by providing a separation cut (10) between the sheets (3, 4) in a position in which the hairpin coil (2) comprises greater-length rectilinear portions (2'A). That part of said longer portions which projects from the sheets (3, 4) is bent to flank one side of said sheets. The evaporator comprises two sections (G, F) of different refrigeration capacity, formed from one and the same hairpin coil (2) which at the point in which said sections join together comprises a loop bent towards one side of said sheets (3, 4).
